Establishing Table Relationships

Now that you know the theory behind the relational model, you can turn your attention to creating and working with related tables in queries. The first step, however, is to establish the relationship between the two tables, which is what this section is all about.

To get started, choose Tools, Relationships (or click the Relationships button on the Database toolbar). You'll see the Relationships window, shown in Figure 3.1. (Note that you'll see this view of the window only if you're working with the Northwind sample database.)
